Table 3-4 on page 33 shows the quantity supported of compute nodes with GPU
trays attached and two 225 W GPUs installed. Only 1300 W power supplies are
supported and only 200-240V AC input supported. The supported 225 W GPUs
are:
Intel Xeon Phi 5110P, 00J6163
NVIDIA Tesla K10, 00D4192
NVIDIA GRID K2, 00J6161
NVIDIA Tesla K20X 00J6165
